Description

Technical Field

[0001] The utility model relates to the technical field of coupling processing, and more specifically to a grinding device for surface processing of a high-speed railway coupling. Background Art

[0002] A coupling is a device that connects two shafts or a shaft and a rotating part. The two shafts rotate together during the transmission of motion and power and do not disengage under normal circumstances. It is sometimes also used as a safety device to prevent the connected parts from being subjected to excessive loads and plays an overload protection role. It is often used between high-speed rail carriages. During the production process, the surface of the coupling needs to be polished and finished.

[0003] Based on the above, the inventors found that the existing grinding devices are generally provided with a rotating structure to rotate the linkage clamping parts, thereby achieving multi-angle grinding and improving the grinding efficiency. However, the rotating clamping parts lack effective supporting components and have poor stability. Therefore, in view of this, the existing structure is studied and improved, and a grinding device for surface processing of high-speed rail couplings is provided, in order to achieve a more practical purpose.
